M. W. Craven was born in Carlisle but grew up in Newcastle, running away to join the army at the tender age of sixteen. He spent the next ten years travelling the world having fun, leaving in 1995 to complete a degree in social work with specialisms in criminology and substance misuse. Thirty-one years after leaving Cumbria, he returned to take up a probation officer position in Whitehaven, eventually working his way up to chief officer grade. Sixteen years later he took the plunge, accepted redundancy and became a full-time author. He now has entirely different motivations for trying to get inside the minds of criminals . . .

M. W. Craven is married and lives in Carlisle with his wife, Joanne. When he isn’t out with his springer spaniel, or talking nonsense in the pub, he can usually be found at punk gigs and writing festivals up and down the country.

Thank you so much to Netgalley for giving me this free advance copy, and I’m writing this review honestly and without bias.
Every time I pick up a new Poe book I always say to myself 'there's no way this can be better the last one' and every single time it is! The genius that is Mike Craven has produced another astonishing story that kept me thoroughly engrossed - the world could have ended and I wouldn't have noticed. This is dark, highly amusing - Nigel Flowers and the carrot had me laughing out loud! Poe and the truly wonderful Tilly find themselves entangled in a world of porn and Chinese triads - how the author keeps coming up with these unique plots is nothing short of brilliant. The pace is relentless, the plot sublime, the characters are so well developed they almost come to life through the pages. Star of the show for me was Towler - loved every single minute of him. This is book 8 and I just cannot find enough superlatives for this author. This is Mike Craven at the very top of his game, and The Killers' Mark is storytelling at the very highest level. My favourite read of the year and unless Mike produces another Poe book before the year is out (a girl can dream!) that's where it is staying. All the stars and a million more for this

Only fellow reading addicts will understand the excitement of starting a hugely anticipated book. Settling down, and opening the first page of a MW Craven, is deserving of a fanfare in my opinion.

Tilly Bradshaw and Washington Poe, to give them their Sunday names, find themselves in uncharted territory. (Side note, I love the business cards)
A most unusual case finds them, brought by the magnificently named Esmeree Blue. Just 15, but with an attitude that earns respect from Poe’s scariest of allies; Esmeree is looking for her mum, Oceane.

I know reviewers say this often, but the Tilly and Poe books are one of my favourite series, right up there at the top. The genuine friendship between these two characters is wonderful. I’m sure most readers would love to be part of their Scooby Gang. I love the character name Vincent du Buk. I wonder if Mike is a Strictly Come Dancing fan? As this name could easily belong to the love child of Vincent Simone and Anton du Beke.

I always read the acknowledgements at the end of a book, as this is where you hear the author in their own words. This was one of the most entertaining acknowledgements that I have read, it had me chuckling away, especially the reference to the curling team. It was so niche, very amusing.

As you can tell, I adore this dark and hugely entertaining series, this book could well be my favourite; but that’s as tricky as choosing which is your favourite child. If you are a fan of the series, I hope you will love this book as much as I have. If you haven’t read this series, head to your bookseller and find The Puppet Show immediately. Then sit back and enjoy.

If I could award more than 5⭐️⭐️⭐️⭐️⭐️ to The Killer’s Mark, I absolutely would.

Thank you to Constable, Little Brown Book Group and M.W. Craven for the opportunity to read and review an advance copy of The Killer’s Mark.

From the very first pages I was completely hooked. What’s in the box? Why is this man a monster? And then… five years later?! I wanted answers immediately.

This is the eighth book in the Washington Poe series and, somehow, it still feels fresh. Poe and Tilly remain my favourite detective duo, and one of the biggest reasons I keep coming back is the humour. I genuinely laughed out loud throughout this book. Whether it’s Poe’s brilliantly dry one-liners, the banter between the characters, or Tilly simply being Tilly. Craven has a way of making you laugh in the middle of some incredibly dark subject matter.

One thing I’ve always loved about this series is how much I learn along the way. Craven seamlessly weaves policing, history and fascinating factual details into the story without it ever feeling like an information dump. I always find myself pausing to Google something because he’s sparked my curiosity. I also enjoyed spotting a couple of little nods to fellow authors, which made me smile.

And then… that murder.

Hand on heart, I think this is the first time a murder in a crime novel has genuinely left me sitting there with my mouth hanging open. It wasn’t just the murder itself, it was the cruelty before and after. The broken dreams. The promises that would never be kept. I actually had to put the book down for a minute while my brain tried to compute what on earth I’d just read. I genuinely think it’s one of the darkest and most twisted moments in the entire Washington Poe series.

The Killer’s Mark is a “just one more chapter” book… except one more chapter turned into staying up until 1:30am because I had to know how it ended.

There isn’t much I can say about the plot without spoiling it, and I never want to do that. Discovering everything alongside Poe and Tilly is half the fun.

Speaking of Poe and Tilly… they’re still my favourite detective duo. I loved seeing Tilly and Estelle teaming up against Poe, and Tilly driving a Honda Jazz just felt so perfectly Tilly. 🤭

Another brilliant addition to one of my all-time favourite crime series. Funny, dark, shocking and impossible to put down. And after that ending… let’s just say I’m already desperate for book nine.

Several years ago, Vice Admiral Boyer dies intestate, leaving his estranged daughter to inherit a sizeable estate. Among the inheritance is an Aegis Box, accompanied by a warning never to open it. Ignoring the warning, she opens the box anyway, unleashing a chain of events that leads to the biggest investigation the National Crime Agency has ever undertaken.

Five years later, Poe and Tilly no longer work for the NCA. Tilly still undertakes important freelance work for Alastair Locke at MI5, but together they now run their own private investigation company, Gumshoes for Hire, based at Cowie House in Carlisle. Business isn’t exactly booming, though, as Poe has turned down every case that’s come their way. One memorable rejection was because he thought the client looked like Ken Dodd, and joked that he had probably just lost his Diddy Men! (If you’re of a certain generation, you’ll get the reference.) It genuinely made me laugh out loud.

Everything changes when fifteen-year-old Esmeree Blue arrives clutching a wallet. The story she tells them immediately piques Poe’s interest, and Esmeree, who is full of sass, hands him £90 to hire them. She wants them to find her missing mother, Oceane Blue, but it soon becomes clear that this case is going to be anything but straightforward. Before long, Poe and Tilly find themselves caught up in something far bigger than they could ever have imagined. Can they find Oceane and walk away unscathed?

I was so excited to get early access to this book before its release in August, and it certainly didn’t disappoint. The author always knows exactly how to entertain. We’re reunited with the characters we’ve all come to love, while also meeting some brilliant new additions who have businesses within Cowie House. What a wonderfully eccentric bunch they are! The descriptions are hilarious, and I could picture every single one of them. One moment I was laughing out loud, and the next I was on the edge of my seat.

I absolutely love this series. This isn’t cosy crime, it’s dark, gritty, and exactly the kind of crime fiction I enjoy. Now that Poe and Tilly are their own bosses, they’re no longer constrained by rules and regulations (although, to be fair, I’m not sure Poe ever paid much attention to those anyway!). Poe has well and truly put himself in the lion’s den this time, facing opponents who are both ruthless and deeply immoral. Thankfully, with Tilly’s incredible brain, Poe’s unique skill set, and his trademark grumpiness, they make a formidable team. The result is a thrilling, addictive read that I was genuinely sad to finish. Now comes the long wait for the next book.

The pace is relentless, with so many twists and turns that you never know what’s coming next. As always, the cast of characters is fantastic. I especially loved Esmeree, her potty mouth had me chuckling more than once, and she was such a refreshing addition to the series. The plot is wonderfully complex and will keep you guessing right to the very end.

And, of course, there is Poe’s food! Plenty of pies and sausage flats make an appearance… although if Estelle asks, Poe definitely had a salad. 😁

This is an easy ⭐⭐⭐⭐⭐ read, and if I could give it more stars, I absolutely would. It arrived at the perfect time, as I was in a bit of a reading slump, but Poe and Tilly always manage to pull me right back out of one. I can’t wait for next year’s instalment and another adventure with this brilliant duo.

The Killer’s Mark is the eighth book in the Washington Poe and Tilly Bradshaw series, and what a cracking series it is.

The book can be read as a standalone, but I’d definitely recommend starting at the beginning so you can get to grips with the finer details of the characters’ backstories (and they’re all excellent reads).

In The Killer’s Mark we follow Poe and Tilly as they start their new venture as private detectives – in Tilly’s words, ‘Gumshoes For Hire’. We’re introduced to Esmerée, a fabulous, feisty new character, and we get to see more of Matt Towler (who I may or may not have a slight crush on!).

The dark, gripping, gritty (occasionally gruesome and gory) story is well-crafted and deftly plotted. The pacing is spot on, and the character development is just superb. All the characters are so well-developed and fully fleshed out; if I didn’t know better, I’d say they were real. The friendship between Poe and Tilly, their banter and sarcasm, and the laugh-out-loud humour are what make this series so special.

Honestly, I can’t find the right words to do justice to this fantastic book (and series). Add it (and the other seven) to your list immediately; you won’t be disappointed!

Many thanks to NetGalley and the publisher for the eARC in exchange for an honest, unbiased review.

The Killer’s Mark is another belter of a book from the dark and severely twisted mind of M.W. Craven. It’s the kind of book you tear through, even though you don’t actually want it to end – ever.

The combination of Poe, an unorthodox and grumpy detective and his fabulous technically brilliant and on the spectrum team-mate, analyst Tilly Bradshaw is tremendous and Poe’s marriage to the excellent pathologist, Estelle has only enhanced this series. What makes this series stand out is the brilliant, scathing sarcasm of Poe and the contrasting wide eyed unworldly innocence of the brilliant Tilly Bradshaw whose tendency to open her mouth and say, completely unfiltered, exactly what she is thinking makes for some fantastically funny moments. That and Poe’s ability to think the unthinkable makes for a great team. Not to mention the food references which come thick and fast, and even extend to the acknowledgements.

This time around, Poe and Tilly Bradshaw have left the National Crime Agency behind and set themselves up as private investigators. The sign on the door might jokingly describe them as “Gumshoes for Hire”, but it doesn’t take long before they find themselves entangled in a case that is anything but light-hearted. What begins with a teenage girl searching for the mother she believed was dead soon develops into a complex and deeply disturbing investigation involving trafficking, pornography and prostitution. Running alongside this is another mystery connected to a retired Vice Admiral, an impenetrable safe and secrets that have already triggered one of the largest investigations in National Crime Agency history.

Poe has adapted to life outside of the NCA. He is the same stubborn, instinct-driven investigator, but he is noticeably happier and more settled than before. His marriage to Estelle has brought a degree of stability to his life without softening the qualities that make him so effective.

The relationship between Poe and Tilly is built on unwavering loyalty and mutual respect, and Mike Craven writes their interactions with warmth, humour and authenticity. Their exchanges made me laugh out loud, even when the investigation itself was heading into some very dark territory.

And my heavens, it is not just dark, but as dark as the mouth of hell. Craven explores some deeply uncomfortable subjects in this novel. The criminal world uncovered by Poe and Tilly is genuinely unsettling, creating an atmosphere of menace that seeps into the pores. Fortunately, Craven has the ability to balance that darkness with genuine humour. The dialogue is witty and sometimes completely absurd, yet it works beautifully. Trust me, you need those blessed moments of relief before the tension ratchets up again.

The P.I. business isn’t doing all that well. Poe keep turning down clients he doesn’t like the look of; literally – he doesn’t like the way they look, and its only Tilly’s side line working for MI5 that’s keeping them in business. But when the teenage Esmereé Blue turns up in the office looking for her mother, Oceane Blue, Poe is intrigued.
Esmeree is mouthy and disrespectful, but there’s a hidden vulnerability there that’s hard to ignore and her story is remarkably strange. From the moment they take the case, Poe and Tilly’s lives are turned upside down and inside out.

The plotting is superb and the supporting characters, whether friend, business neighbours, or deadly foe, are just fantastic. The pacing is spot on, unfolding steadily as we get to grips with Poe and Tilly’s new lives, before accelerating into a gripping, tension fuelled thriller. From the beginning, this is a book that it’s impossible to put down. I think it might be my favourite in the series so far.

Verdict: The Killer’s Mark is another winner from M.W. Craven. It delivers everything I look for in a crime thriller. With a compelling mystery, unforgettable characters, emotional depth, sharp humour and plenty of tension. Poe and Tilly are up there as one of the best partnerships in crime fiction. Dark, gripping, witty and (as I’ve said before) as addictive as crack cocaine, The Killer’s Mark is a compulsive and compelling 5 star must read. It is unmissable for any crime fiction fan.

"Poe sighed. When he'd called Bradshaw and asked if she knew what to do, he'd assumed it was obvious. She was to call his wife. Get the Doyle family solicitor on the case. She wasn't supposed to call one of the most senior spies in the country."

My Rating: 5⭐️⭐️⭐️⭐️⭐️ LOVED THIS!!! Tilly and Poe say no more!!

A MONSTER. A MOTHER. A MURDER?

When Vice Admiral Boyer, RN (retd) died without leaving a will, his estranged daughter inherited his - not inconsiderable - estate. Called home to sort through his belongings, she found an AegisBox - a tamper proof safe within a safe designed to self-destruct if anyone without the code attempts to open it. Unable to walk away without the truth, she uncovered something so horrifying it launched the biggest investigation in the National Crime Agency's history. Five years later, Washington Poe is unwittingly, and unwillingly, sucked into its gravity...



Finally able to escape the authority they railed against, Washington Poe and Tilly Bradshaw are enjoying their new jobs as private detectives or - as the sign on their door says - 'Gumshoes for Hire'. When a teenage girl walks into their office, looking for the mother she long believed to be dead, they agree to take the case. As Poe and Tilly investigate the girl's claims, they find themselves drawn into a murky world of trafficking, pornography and prostitution. Will they be able to help the girl find her mother, or will the dark forces at work, who will stop at nothing to protect themselves, get there first...


Well… as soon as I saw this on NetGalley I snapped it up… well I hit that request button quicker than you can say time for dinner…. I wasn’t expecting to get it as I have never gotten an M.W. Craven before on NetGalley and I was ecstatic when I woke up the next day and was approved. I am not going to lie, I knew I would love this… why… well I always love these books. Even when they don’t sound as interesting as I would like, or even when they have themes that I normally steer clear of, I always love them.

I’ll be really honest I didn’t even read the synopsis. I just hit that request button and started reading the minute it landed on my kindle.

I wasn’t disappointed and I doubt I ever will be. I love this series, I love the writing and I love these characters. The only gripe I ever have is that it ends and then I have to wait another year for Mr Craven to write me a new book to snap up the minute I can.

I was wondering how this would play out with Tilly and Poe not working for the “Man”anymore and out on their own as GumShoes for Hire… I thought will this work… Pffft don’t be friggen stupid Karly of course it worked. Everything that Tilly and Poe do works…

It is always dark, and murdery, its got thrills and spills but always laughter and a bit of aww moments. This is no different. I love the friendships and the relationships, the tricks and the spies. Its all in here… and I love every single word.

Would I recommend, you bet your arse I would recommend. Would I say jump in at number 8, clearly you don’t know me if you think I would do that. I absolutely categorically do not recommend jumping in at number 8 I just dont think you can enjoy it as much as if you know the entire history. And look I’ll level with you, if you aren’t willing to go back to the beginning you don’t deserve number 8 … harsh… but true. This is a series that you will love from number one so don’t rip yourself off.

Overall - READ IT, LOVE IT AND THEN READ IT AGAIN!!!

Thank you to NetGalley, Little Brown Book UK Constable, and M.W. Craven for an advanced copy of this exceptional book in exchange for my honest review.

There is an army of Poe and Tilly fans out here who eagerly wait for the next book in this series. I am a loyal foot soldier in that army. Every summer we are treated to another episode, and every summer we wonder just what the author has in store for his characters and for us.

The Killer's Mark finds Washington Poe and his colleague Tilly Bradshaw heading up their own private investigation business, or as it states on their sign; 'gumshoes for hire'.

Both Poe and Tilly have changed over the years; they are now able to be their own boss, although Tilly is still contracted to do some very high profile, and confidential work for MI5. Whilst Poe still owns his isolated cottage on the moors, he now lives in his new wife Estelle's ancestral stately home - with a butler! What hasn't changed at all is their relationship and it is as warm and as darkly funny as ever, in fact I laughed out loud more times than I can remember!

Poe is affected by events from past books, his vulnerabilities do show through and he's loathe to take on new cases. He'll find every excuse to turn away a client. including the fact that he thinks that they look like Ken Dodd (IYKYK)!

And then, from the moment fifteen-year-old Esmeree Blue appears on Poe and Tilly's doorstep, it's obvious that this isn't going to be an ordinary case. Clutching a wallet and armed with plenty of attitude, she confidently hands over £90 and asks them to find her missing mother, Oceane Blue.

It's an unusual request, and one that immediately captures Poe's attention. Esmeree is a fabulous character; sharp, determined and she is impossible to ignore. However, what initially looks like a straightforward missing persons investigation soon takes an unexpected turn. Before long, Poe and Tilly are drawn into something much darker and far more dangerous than either of them could have imagined.

As the mystery deepens, the tension builds beautifully, with twists and surprises around every corner. Finding Oceane is only part of the challenge; staying one step ahead of the danger that surrounds them may prove to be the biggest test of all.

One of the many reasons why I love this series so much is the author's ability to balance the darker aspects of the story with perfectly judged humour. Just when the tension threatens to become overwhelming, there's a witty exchange or a moment of banter that reminds you why these characters are so special.

Poe and Tilly remain one of crime fiction's most fabulous partnerships, they're an absolute joy to spend time with. Theres is also an impressive supporting cast, and it's always a pleasure to see familiar faces reappear. They add real depth and warmth to the novels, making each new instalment feel like catching up with old friends.

However, don't be fooled into thinking this is an easy read! Underneath that humour lies a dark, gripping and often unsettling story. The investigation is packed with twists, mounting tension and real danger, while tackling some difficult subjects, including abuse, organised crime, trafficking and murder. It's compelling, thought-provoking and, at times, impossible to put down.

Brava Craven, you did it again! Highly recommended.

What can I say about the Washington Poe series that has not already been said? Brilliant narrative? Of Course. Biting wit and dry humour from Poe? Without question. Action and danger that will test all of the team's skills while drawing on help from possibly the most untrustworthy, but supremely connected, of allies? Well, that's just another day on the job for Poe and his partner in crime solving, Tilly Bradshaw.

But this time around, the pair have to act without the full force of the law on their side. In fact, given the opportunity, some of the Police they come into contact with would gladly see it turned all the way against them. Because this is the start of a new ear for the pair. No longer a part of the National Crime agency or any other government backed law enforcement agency (well, apart from Tilly's side gig, but that's another story). Now they are 'gumshoes for hire' and their case if going to lead them into a totally unexpected, and ultimately very dangerous, new world.

I liked this book. A lot. Love what the author has done here in creating a hole new dynamic for the team. If you have ever wondered what Poe would get up to unencumbered by the small matter of 'the law' and 'police procedure', well all of your questions are about to be answered. And it all comes about courtesy of their new client, Esmerée Blue. It's fair to say that she is not your average client. She's not even the average age of the kind clients you might expect private investigators to have. Not that they have many, also another story. But when it comes to having a smart (potty) mouth, ingrained cynicism, and a not at all quiet intelligence, lets just say that Poe has definitely met his match. I liked Esmerée, liked her street smarts, and her more than occasional snarkiness, but given her backstory that was understandable. The author has created a brilliant new personality here, and she adds that special 'strength in vulnerability' edge to the story that made me totally invested in the case.

Now this is a Washington Poe story so there is a darker edge to it. Perhaps not quite as dark as some of its predecessors, but not lacking in threat or jeopardy in any way. There are moments of real jeopardy and, even if the threat isn't quite so obvious from the opening chapter, it creates that kind of unease, that feeling that something is greatly amiss, a sensation that is only strengthened the more we journey into the investigation and the full ramifications of the case become clear. So yes, I've read darker, but this hits the spot, creates the emotional tension, for completely different reasons.

As well as Poe and Bradshaw, the book features faces old and new, with cameos from one of their former colleagues, and a lsightly larger role played by someone who it's clear Poe reluctantly tolerates, but who really steps up when necessary, if only to protect their asset, aka Tilly. Yes, Alastor Locke is back, and whilst he has has lost none of his particular brand of charm (?), his presence and the back and forth dialogue between him and Poe did make me smile. It's a set up that shouldn't work, especially given their history, but totally does, and a great ally for the pair to have. Not that he can do anything Tilly can't, information wise, he just comes with a fancier car and access to a lot of well trained, and armed, men and women.

Full of the wit, tension, action and brilliant storytelling I have come to expect from the series, I'm really looking forward to seeing the development of this new era of Poe and Bradshaw, 'Gumshoes for Hire'. I have a feeling it is going to be a hoot. Definitely recommended and, as ever, worthy of one of these too. The Red Hot reads badge. If you don't love it, I just don't know what's wrong with you (although I'm sure Poe and Esmerée would find a few names for it).

Can you see me happy dancing, clutching Kindle in hand with the arc of the latest Poe and Bradshaw, arguably one of the best crime series out there?

Several years ago, Vice Admiral Boyer dies intestate and his estranged daughter inherits all his considerable estate, including an AegisBox. She opt to open it despite warnings and it’s contents launch the biggest investigation the NCA (National Crime Agency) have ever undertaken. Five years on, Poe unwittingly will be drawn into it.

Poe and Bradshaw are now “ gumshoes for hire” which they run out of Cowie House in Carlisle, although Tilly still uses her not inconsiderable talents for MI5. Currently, they have no cases, partly because Poe rejects 22 as they’re not sufficiently interesting, that is until sixteen year-old Esmerée Blue arrives clutching £90. The story she tells does interest Poe and a paltry £90 exchanges hands. Initially, the search involves looking for Esmerée’s mother Océane but it soon becomes clear. It’s WAY more than that. Very dark forces are at work here, let’s hope our intrepid duo emerge unscathed.

I’m running out of superlatives to describe this incredible series, I quite simply love it and being in the company of Poe, Bradshaw, Estelle et al for a few hours is entertainment of the highest standard. I start laughing right from the beginning with the hilarious descriptions of fellow occupants of Cowie House. MWC is a genius, combining laugh out loud humour (I lose count of the amount of times) with such original descriptions with the darkest jet black plot lines where there’s layers of grit upon grit. This time Poe enters the metaphorical lions den, danger piles on danger, cages aren’t just rattled, they’re positively shaking the doors off. They’re up against the unspeakably cruel and immoral but fret not, there’s Poe’s quick thinking and resilience (with a side order of grumpiness) an even more devastating for those foolish enough to take them on and expect to win, there’s Bradshaw’s incredible brain which is a thing of beauty, speed and unbelievable creativity.

The pace is fast, there are more twists and turns than Lombard Street, there are characters that are larger than life, it’s complex, intelligent and brilliantly written. It’s a thrill from start to finish. I’d like to give a big shout out for Esmerée, like Estelle, I fall in love with her, potty mouth and all. Finally there’s food, lots of food, Poe likes a pie amongst other things generally no good for his health, be sure to tell Estelle he’s had salad.

Overall, if you think Eddie Flynn is clever, you haven’t met Washington Poe and Tilly Bradshaw, they’re even cleverer, if there is such a word, Tilly will know. FANTASTIC. Five stars all the way and I can’t wait for the next instalment.

With thanks to NetGalley and a huge thank you to Little, Brown Book Group, Constable for the much appreciated early copy in return for an honest review.

Teenager Esmerée Blue seeks the help of Washington Poe and Tilly Bradshaw to find her mother, a person she long thought was dead. The quest leads to a dark and dangerous confrontation for everyone involved.

The Killer's Mark by M. W. Craven is the eighth book in the Washington Poe series, a series that just keeps getting better and better. The author has taken the books in a new direction, with Poe having left the police force and set up as a private investigator with his friend Tilly Bradshaw. This makes this book an ideal starting point for anyone new to the series, but I really would recommend reading the series right from the beginning so you can see how the characters have developed.

Even though the duo has set up business as 'Gumshoes For Hire', Poe is reluctant to actually take on any cases until a teenage girl asks for help. Esmerée explains how she lived in New York with her mother, Océane, who was the mistress of an extremely wealthy man, until her mother murdered the man and fled, leaving Esmerée to fend for herself. Esmerée has always believed her mother to be dead, until she recently caught a glimpse of her in a pornographic film.

Having previously been involved in the hunt for serial killers, fans of the series will be used to the dark tones that frequently appear, and The Killer's Mark is no different. The villain of the piece this time around is the Triads, an organised crime group that has almost mythical status within the UK, easily causing fear at the mere mention of them.

There are times when you would assume Poe and Tilly are going to be hampered as they no longer work for the NCA and cannot rely on the backup it provided. No longer constrained by the rules he had to follow as a police officer (and let's be honest, Poe and rules had a very flimsy relationship), we see a much more gung-ho side to Poe, and as a result, some decidedly tricky situations to be extracted from. Thankfully, the pair have a network of ex-colleagues and friends they can call on. Tilly's work for the security services plays a prominent role in the storyline.

With Poe now being his own boss, he no longer needs to think before he speaks; fans know that kowtowing to authority was not one of his strengths. As a result, the level of sarcasm is high. Add to the mix a feisty American teen, and I found myself laughing out loud repeatedly.

As the conclusion approaches, the pace never lets up, and the level of danger seems to increase exponentially. Shocking revelations are uncovered, with a satisfying resolution leaving so much scope for the future.

Poe and Tilly have a new private investigator business.

I have a feeling The Killer’s Mark is going to be impossible to review because I absolutely do not want to give away spoilers. As soon as I had read the Prologue I knew this was going to be an extraordinary book. It is. It also confirms my suspicions that M. W. Craven is both terrifyingly skilled and possibly a little unhinged – in the best possible way – as no ordinary mind could construct this kind of plot.

As ever with a Poe and Bradshaw book the pace is blistering, the short chapters refuse to let the reader step away from the narrative because, not only do they add momentum, they are so gripping with those trademark hooks at the end of each one that it’s impossible not to want to read on. The twists, the balance between keeping the reader informed and withholding just enough to have them completely ensnared in the narrative thrums through the pages. The trademark visceral nature of the story, the wit, humanity and technological science with which we are so familiar in a Washington Poe book are wonderfully resonant and yet feel fresh and vibrant within The Killer’s Mark. The main characters might be familiar but there is nothing repetitive or derivative in the storytelling. M. W. Craven is innovative and mesmerising with an assured sense of detail that is utterly convincing.

Indeed, alongside a plot that is insanely intricate, brilliantly constructed and mind-blowingly entertaining, there is some fabulous character development here. If you’ve not read another of the Washington Poe books, there is enough of Poe’s past exploits referenced to give a rounded picture, but in The Killer’s Mark, he is given a slightly more tender trait so that his humanity is both presented more fully and tested to the limit. What I loved even more this time is that Tilly is becoming adept at her own deviousness too. The balance of familiarity and progression is so appealing. Add in the teenage, angst-ridden, foul mouthed Esmeree to the mix and the combination is both explosive and fascinating.

I’m aware I’ve said nothing at all about The Killer’s Mark – deliberately so as I really, really don’t want to spoil the read for others. However, one aspect I am willing to spoil is that the Epilogue, particularly the final sentence, made me cheer, but you’ll need to read the book to find out why!

Regardless of my inability to review it, I thought The Killer’s Mark was excellent. I absolutely adored being back with Poe and Tilly. I loved the attention to detail, the evident thorough research that has gone into making this another authentic and pulse elevating narrative, and the masterful storytelling which all add up to another roller-coaster ride. Don’t miss this one because it’s brilliant and if you haven’t read the other seven books in the series you are really missing out!

The Killer’s Mark, is the eighth book in the Washington Poe series by M.W. Craven. This is one of my favourite series and always eagerly await the next book. The intriguing combination of Washington Poe and Tilly Bradshaw is entertaining enough before you add the well thought out plot. Washington Poe is a disgraced ex policeman who doesn’t hold back and together with the socially inept Tilly Bradshaw who although is a genius has lived a very sheltered life form an entertaining partnership. Together they form not only a great crime duo but also really enjoyable reads. In this latest novel they move away from the formal constraints of official law enforcement, to a multi-layered conspiracy thriller that brilliantly anchors a deeply personal missing persons case to a massive, dark institutional cover-up.

The investigation begins with the death of Vice Admiral Boyer, a retired Royal Navy officer who passed away without leaving a will. His estranged daughter, arriving to sort through the considerable estate, discovered a highly secure piece of military-grade tech: an AegisBox. This tamper-proof safe-within-a-safe is engineered to violently self-destruct if anyone attempts to open it without the proper code. Driven by a need for the truth, she bypassed the defense mechanism and unlocked the box. The contents were so universally horrifying that they triggered the largest, most secretive investigation in the history of the National Crime Agency (NCA). Five years later, the shockwaves of that discovery are still rippling through the underworld—and Washington Poe is about to be pulled directly into its gravity well.

In the present day, Poe and Tilly have finally managed to escape the rigid bureaucracy of the authorities they spent years railing against. They are happily embracing a new chapter as independent private investigators, complete with a quirky sign on their door: ‘Gumshoes for Hire’. What begins as a standard missing persons file quickly unravels into a descent into absolute darkness. As Poe uses his sharp intuition and Tilly deploys her unrivalled analytical mind, their investigation pierces the veil of a highly dangerous criminal network involved in human trafficking, pornography, and prostitution.

A gritty thriller with an injection of witty humour. A clever plot with the mystery of the five-year-old AegisBox and how a retired Vice Admiral’s terrifying secret connects to a modern-day street-level trafficking ring.

I would like to thank both Netgalley and Little Brown Book Group for supplying a copy of this novel in exchange for an honest review.

It's been a few books since I have managed to snaffle me an advanced copy of a Tilly & Poe book but the ARC deities were smiling at me when they approved my request for this, the 8th book in said series. Now, you know what s coming next... Although I actually can't believe that there is anyone who reads this genre who hasn't at least started this series. But I am going to bang that drum and suggest, if you haven't already, please do go back to The Puppet Show and read in order.
Anyway... to be honest, if you have been with this series from the start and are still reading it, all's you need to hear, if you indeed need to hear anything, is that it's brilliant as expected and you should just go read it...
We start with a scene where the estranged daughter of a recently deceased Vice Admiral has just found out that, due to a lack of a will, she has inherited his estate. When we catch up to her, she is opening his safe and, inside, finds an Aegis Box (tamper proof safe within a safe) what is subsequently found inside that will send horrific shockwaves which launches the biggest investigation the NCA has even seen...
Meanwhile, Tilly and Poe have left the force and set up shop as private investigators. Finally Poe has the ability to do what he wants without worrying about consequences or sanctions from the powers that be. Although he still has to answer to Tilly... obvs! His latest "walk-in" client is a teenaged girl who is looking for her mother who she thought was dead but who had appeared in a recent "video" she recently watched!
And so begins what is probably my new favourite book in this series. Although I think I say that every time and fully expect to say the same next time! It's not pretty, it contains some nasty stuff. But then, if you have read this series before, you'll know that the author never pulls his punches.
But, again as usual, he also peppers the dark stuff with some really great humour, and cracking banter, especially between Tilly & Poe. And don't forget, Poe's now a married man, so we have more of Estelle too - yay!
I could bang on and on abut how brilliant this series is. It's one I usually revisit time and time again on Audiobook, and also, one of the rare series that I share the love of with my "not as much a reader" brother who, and he will be delighted to know, is now the recipient of my first in the queue reserved library loan for this book being as I snaffled me the ARC, which I thank the Publisher and Netgalley for!

I’ve now read every book in this series, and The Killer’s Mark reminded me exactly why I keep coming back for more.
This time, Poe and Tilly have left the National Crime Agency behind and set up as private investigators, or as the sign on their office says, “Gumshoes for Hire.” It was great seeing them in a completely different role while still getting exactly what makes this series so addictive.

Washington Poe and Tilly Bradshaw are the heart of this series. Their friendship, humour and unwavering loyalty make every story unforgettable. Their witty banter is a welcome break from the darker moments and is one of the reasons this series stands out from so many other crime thrillers. I can’t imagine one without the other.

Esmerée Blue was a brilliant addition to this book. As the person who brings Poe and Tilly their latest case, her search for answers sets the whole investigation in motion. I really enjoyed getting to know Esmerée. She is complex, determined and feisty, and her journey added another layer to the mystery while keeping me invested in discovering where the truth would lead.

The investigation starts with what seems like a straightforward missing person case but quickly develops into something far darker. The story explores difficult themes, including trafficking and sexual exploitation. M.W. Craven handles these topics with sensitivity while keeping the mystery compelling and believable.

As always, the plot is cleverly constructed with plenty of twists, red herrings and moments that kept me questioning where the story was heading. Every chapter seemed to raise the stakes, and I was constantly second guessing where the investigation was heading. Just when I thought I’d worked it out, another revelation completely changed my mind. The plot is brilliantly crafted, and the characters continue to shine.

If you’ve already fallen in love with this series, this instalment won’t disappoint. If you haven’t started the Washington Poe books yet, begin with book one so you can fully appreciate the characters, their development and the journey they’ve been on together.

This is exactly the kind of intelligent, character driven crime fiction that keeps me coming back to this series. Another outstanding addition to one of my all time favourite crime thriller series, and a series I can’t recommend highly enough.

A huge thank you to NetGalley and the publisher for the ARC. As a massive fan of this series, I was absolutely thrilled to be approved to read and review The Killer’s Mark. All opinions are, of course, my own.

I honestly don’t know how M.W. Craven does it.

Eight books into the Washington Poe series and not one of them has disappointed me. The consistency of the writing, the storylines and the sheer imagination that goes into each book is astounding, and The Killer’s Mark is no exception.

There are opening chapters, and then there are OPENING CHAPTERS. From the very beginning, this book had me completely hooked. I started it and suddenly found myself nearly 40% through because I genuinely could not put it down.

One of the things I love so much about this series is the characters. Poe is just brilliant, and some of his one-liners and exchanges with the other characters genuinely had me laughing out loud, which feels slightly wrong when you’re reading a thriller! And Tilly… I’m constantly gobsmacked by the things Craven comes up with for her. The knowledge, the ideas, the way her incredible brain works and the part she plays in solving the seemingly impossible. I honestly don’t know where he gets it all from.

And then there’s the suspense. By the time I reached the final stretch, my heart was in my mouth. At 92% I still had absolutely no idea how it was going to end. The suspense was well and truly suspensing!

I absolutely devoured this book, which was actually slightly bittersweet because I desperately wanted to know what happened while simultaneously not wanting it to end. Knowing this is the newest book in the series and I don’t have another Poe waiting for me made finishing it even worse!

I recommend this series to every thriller lover I meet. Eight books in and M.W. Craven is still producing incredible, clever, gripping stories that keep me guessing until the end. I absolutely loved The Killer’s Mark.

And if that epilogue is anything to go by, I’m desperately hoping there is more Poe and Tilly to come. Please don’t make us wait too long!

Just finished reading this book which is not out until 13th August but I couldn’t wait to share how good it was - I was delighted to receive an ARC, from @netgalley of M W Craven’s latest and eighth book in his Washington Poe series as I’d read so many good reviews about this collection of crime novels. And OMG this certainly lived up to the hype, I devoured this book, so safe to say, I’m now going to start at the beginning and read the whole series.

This one throws readers straight into a tense, dark and twisted case with the prologue- when Vice Admiral Boyer of the Royal Navy dies leaving his estate to his estranged daughter Wendy, she uncovers a secret so terrifying it prompts an inquiry by the National Crime Agency. Meanwhile, five years later private investigators Washington Poe and Tilly Bradshaw are hired by American teenager Esmeree Blue to find her mother, and in doing so are forced to investigate a major organised crime gang dealing in prostitution, pornography and human trafficking.

I was new to this author and went in with no expectations but quickly found myself laughing out loud, enjoying the smart and witty humour of the characters which added a levity that was much needed to counteract the dark themes of the book.

Washington Poe and Tilly Bradshaw are standout characters, their wit, intelligence and ability to stay one step ahead are what make this story such an entertaining read. Both socially awkward, the highly intelligent Tilly and quirky, ex-cop Poe have a mutual respect and tenderness in their relationship which is uplifting.

Told in seven parts, and set around Carlisle England, the plot was complex, bold and original with dark themes throughout bringing the reader into the murky world of Chinese triad gangs, and I just could not put it down. This was pure thriller-writing perfection for me and an easy five star🌟read.

Many thanks to @netgalley and @littlebrownbookclubuk for the ARC.

Another excellently crafted winner in this wonderful series- I even managed to read it in the Lake District where some of it is set and where I believe the author and Poe reside. I even had Poe’s Croft’s position pointed out to me as we were driving across Shap Fell with a local! Joy of joys!
In this book Poe and Tilly have set up as private detectives after Poe has left the crime agency. Now married to Estelle, Poe lives in her Manor House when in Cumbria, often joined by his crime fighting partner, Tilly.
One day a teenager enters the office and Tilly insists that they take her case - Esmeree begs them to find her long lost mother whom she thought dead.
Esmeree has trailed her to England from the States but the trail had gone cold until she spots her mother’s unique tattoo on a porn video.
Although initially reluctant to take the case Poe comes to like the plucky teenager and proceeds to investigate uncovering a murky plot full of nasty villains who will stop at nothing to protect their business including targeting Poe and those he holds dear.
I really enjoyed the fast moving plot and loved catching up with Poe and Tilly who are now using their unique skills to catch villains as “Gumshoes” for hire. Tilly’s high level intelligence is put to good use and as ever I enjoyed the humorous banter between these characters.
The research into the dark industry portrayed in the book has been thoroughly carried out and made the plot all the more believable but the touches of humour lighten the plot.
Definitely a five star read - highly recommended to Poe and Tilly fans plus a suggestion to read all books in the series for those who have never come across Poe and Tilly before.
I certainly cannot wait for the next book featuring these quirky characters- there was a suggestion of what is to come in the last few pages of this book increasing the level of expectation and excitement!
Thanks to NetGalley and the publishers for my advance copy.

M.W. Craven delivers another gripping instalment in the Washington Poe series with The Killer’s Mark, and once again proves why this is one of the most addictive crime series around. Now operating as gumshoes for hire with their own private detective agency, Poe and Tilly take on a case that initially seems easy to ignore,until it isn’t.

When a young girl Esmeree approaches them, convinced her supposedly dead mother has appeared in an adult film, Poe is intrigued.What follows is anything but straightforward. The investigation spirals into a dark and complex world of Chinese triads, buried secrets, and the seedy underbelly of the porn industry. It’s gritty, unsettling at times, yet balanced perfectly with the humour and sharp banter that makes this series so special.
The dynamic between Poe and Tilly remains one of the greatest strengths of the books. Their relationship is, for me, one of the best in crime fiction, full of warmth, wit, and loyalty. Poe’s instinct to protect those he cares about, even when he barely knows them which adds emotional depth to the story.

Esmeree is a brilliant addition to the cast,feisty, outspoken, and instantly likeable. She fits seamlessly into the gang, and I’m already looking forward to seeing more of her in future books.

The plot is as always brilliantly executed. While perhaps not as overtly violent as some earlier entries, it doesn’t lose any of its tension or impact. There are clever nods to previous books, rewarding long time readers, but this can still be enjoyed as a standalone. That said, starting from the beginning with The Puppet Show will give you a deeper appreciation of these fantastic characters.

Book eight in the series, and somehow it just keeps getting better. I’m already counting down to book nine. If you haven’t started this series yet, do yourself a favour clear your diary, because once you begin, you won’t want to stop.

Washington Poe and Tilly Bradshaw have started their new roles as private investigators and take on their biggest case, when a young girl walks into their office looking to find the mother she has long thought dead. As they investigate they are drawn into a world more dark and dangerous than they could have imagined. Will they be able to help the girl when they are against forces who will stop at nothing to protect themselves?

A new Poe and Tilly thriller is a cause for celebration - it is no secret that this series and author is one of my highest rated, so I was very excited to be able to read the latest addition. This was every bit as good as the previous in the series and I could not turn the pages fast enough. Even though this was quite a long book, it remained addictive and fast paced through out, never with a dull moment. The storyline ended up being clever and original, whilst also having the trademark dark humour and grittiness I have come to expect.

It was fun to see Poe and Tilly in a different setting to usual, discovering how the dynamics of this would work. I wasn’t sure at first if this would work as well, but I needn’t have worried, as if anything, they get involved in even more drama and rule breaking. I also enjoyed seeing links to some of the previous books in the series, as well as new and recurrent characters, especially Towler and Esmeree. The conversations between them all and things they got up to had me laughing out loud at some points, however the author also managed to explore disturbing topics well and keep up the tension and suspense.

This has ended up being one of my top books of the year. I definitely urge others to read this series if they haven’t already and am jealous of those who get to discover them all for the first time. An easy five stars. Thanks to NetGalley and the publisher for this copy in return for an honest review.

A new Craven book is always a highlight of the reading year for many.

Freed from the constraints imposed by their former positions with the British National Crime Agency, Washington Poe and Tilly Bradshaw are now enjoying their new jobs as private detectives or – as the sign on their door says – ‘Gumshoes for Hire’. When a foul mouthed teenage girl known as Esmerée Blue walks into their office, looking for the mother she believed to be dead, they agree to take the case. As Poe and Tilly investigate the girl’s claims, they find themselves drawn into a murky world of trafficking, pornography and prostitution. They are also drawn back into the sphere of the National Crime Agency, who are in the midst of a major investigation sparked by a horrific discovery in the safe of a former British Read Admiral.

The Killer's Mark is a wild ride of a novel. The book gets off to an intriguing start with the discovery within the Rear Admiral’s safe and the unusual way that Esmerée discovers that her mother is possibly not dead. The pacing is then brisk from the opening chapters, and there are the twists and surprises you expect from a Craven novel as the book races to the devious conclusion. Craven employs a number of familiar ploys to advance the action, helped along by Poe’s usual provocative approach to life and some mild humour. There are also the other Craven hallmarks: lots of interesting information, surprising twists, exaggerated characters, witty banter, touching moments and the always engaging Tilly Bradshaw. It is also good to be re-acquainted with the rough and ready Towler and Craven’s other regular characters.

A fair suspension of disbelief is required, but overall it is very good fun.

For me, probably closer to 4 than 5.

Yay! Washington Poe and Tilly Bradshaw are back in Book 8 of the series and it’s another immensely entertaining dark thriller. Spoiler incoming if you haven’t read the previous book so please stop now. Poe has retired from the NCA (police) and although Tilly still has a role in the security service they have set up their own PI business ‘ Gumshoes for Hire’ in Carlisle. It is in fact the only one in the town and it suits Poe so much he turns down every potential job! If you have read any of this authors books before you know that you’re in for an exciting ride as soon as you open the book at page one.

Briefly , everything changes when a foul mouthed 15 year old American girl, Esmerée Blue, bursts into their offices demanding they find her mother who, she says, abandoned her in the US and has disappeared. She assumed she was dead until she recently saw a porn film and spotted a tattoo that she knew could only be her mother’s. As a seriously sordid story unfolds Poe, Tilly, Esmerée and Poe’s wife Estelle find themselves in various life threatening situations.

I think this is the best book of the series so far and love the way the relationships continue to develop. Tilly remains the star of the show for me and there is nothing I enjoy more than the dry humour that regularly sallies forth so innocently. The plot is excellent and expect dark and gritty but not as graphic as some previous outings. Poe’s eating habits made me smile, not the gourmet food the author enjoys! Honestly if you haven’t read this series do get book one and give it a go. You can thank me later. A wonderful read that had me on the edge of my seat. Loved it.

Tilly and Poe are back and this crime reader is cheering! I love this duo, this series, this writer. If you haven’t read it yet you are missing out, go and get The Puppet Show and thank me later.

This is book 8 and they just keep getting better don’t they?! i binged this over 2 sittings, it would have been one if I didn’t have to get up for work. I have listened to the last few in this series and I was reading it in the narrators voice. I was thrilled to be given access to an early copy, thank you so much Little, Brown Book Group UK.

Tilly and Poe are now working as gumshoes for hire at their own private detective agency in Carlisle. Poe has been reluctant to take in any cases so Tilly demands that they take the next case that comes in. And what a doozy of a case it turns out to be. 15 year old Esmeree asks them to find her mother, a mother she thought was dead until recently.

This is not an easy read as it tackles some disturbing subjects and has scenes that made my stomach churn. Poe finds himself chasing down Chinese triads and deeply investigating the porn industry. With friends in high places from his former employers, and together with Tilly’s brilliant mind and computer skills they find themselves up against some formidable characters.

What I love the most about this series is the characters and their relationships. The banter is hilarious, they are dealing with the darkest of the dark and the humorous lines and insults help to keep them sane. A fun new character who will keep them all on their toes is introduced and it was interesting to see the characters interact with her.

One of my books of the year, it was brilliant.

Out on August 13th, I am already anticipating book 9!!

Washington Poe & Tilly Bradshaw; Gumshoes For Hire

Poe and Bradshaw are back! Having left the NCA, the pair are starting their new gig as Private Investigators, or as Tilly likes, Gumshoes For Hire.

When foul-mouthed American teen Esmeree Blue shows up looking for help finding her lost mother, Poe and Tilly take her case (although less enthusiastically from Poe), and find themselves deep in the dark, dismal, world of pornography.

We already know that Poe can be a bit of a loose canon and can stretch the law thin at times, so seeing how he develops without the confines of the NCA, but without their resources, makes for a great change of pace which keeps the world fresh in this fantastic 8th instalment.

But worry not! If you were thinking there would be less "Poe&Tillyisms", you would be mistaken. Before we even get into the meat and spuds of the story, we have some gems:

"The girl rolled her eyes. Said 'Is this asshole the other gumshoe?' 'She says the bottom thing a lot,' Bradshaw explained."

""If you so much as raise your voice to Indica, I'm going to take her gun and tattoo "NONCE" on your stupid sloped forehead. Do we understand each other?""

The Killer's Mark releases 13/08/2026 and available from your usual bookish habitats.

SPOILER - Despite the title, the killer is not Mark. Poor Mark, he isn't even in the book and he's getting accused of being a killer!

Thank you NetGalley and Little, Brown Book Group for an eARC of this book in exchange for my honest review. As a huge fan of M. W. Craven’s Washington Poe series, I was so excited to receive an advanced reader copy of The Killer’s Mark.

Following the events of the previous book, which saw Poe leave the NCA to establish a private investigative firm, I was genuinely curious, and a little apprehensive, about how this new direction would play out and whether the series would hold up.

In this installment, Poe and his brilliant analyst partner, Tilly Bradshaw, find themselves navigating the murky waters of the private sector. Freed from institutional red tape, they must rely on their own with their unconventional methods to crack a new mystery. After a slow start not taking on any new cases, Tilly convinced Poe to take on the next case that walks through the door.

While the setup naturally feels a bit different from the previous books, it is just as gripping and deeply enjoyable. All my favorite characters are back but for me, the absolute highlight of this series remains the dynamic between Tilly and Poe. Their relationship is so distinct, endlessly entertaining, and genuinely heartwarming. It was fantastic to see them teaming up once again. Operating privately means their methods have become even more unconventional, chaotic, and boundary-pushing, but that is exactly what I’ve come to love about this series. A fantastic continuation that proves Poe and Tilly are brilliant in any setting!

Thank you to NetGalley for the opportunity to read this advance copy.

As usual, I wanted to finish this book in one sitting. As a long time fan of Washington Poe, Tilly and the wonderfully eclectic cast of recurring characters, every new instalment goes straight to the top of my reading pile. I always end up binge-reading them and then immediately regret getting to the end so quickly.

This time I showed a little more restraint and spread it over three days instead! If I had any doubts about whether M.W. Craven could keep the series feeling fresh after so many books, they disappeared within the first few chapters. The combination of an inventive case, the Triads, Red Channel and an alien hand attached to Esmeree made for another completely original story that only Craven could pull off.

One of the reasons I love this series is the relationship between Poe and Tilly. Their partnership is as sharp, funny and heartwarming as ever, and I never tire of seeing them bounce off each other. The supporting characters feel like old friends now, and each one brings something different to the story.

The plot is brilliantly constructed, full of unexpected turns, but never so complicated that it loses its way. Craven has a knack for blending dark humour, fascinating forensic detail and suspense into something that’s completely addictive.

Another outstanding addition to one of my favourite crime series. I already can’t wait for the next one.

have just finished #The KillersMark by @m.w.craven which is published by Constable/@littlebrownbookgroup_uk in August

As always with Mike's books this installment of the Poe & Tilly series is absolutely superb!
The plot is so unique ( where does he get his ideas from!? ) and the cast of chrachters jump off the page. The Killers Mark is also bloody hilarious! To mix cruelty, gore and dark humour is always superb in my world...i laughed out loud a lot - especially to "Hello, John" .....( gotta new motor!) ... makes sense when you read the book!

There is a underlying theme of family, belonging & love in this latest book and juxtaposed with the gore it really works SO well! I adored one of the new chrachters and hope they will feature in future books... no spoilers!

The pace was fast & gripping and i tried to read slowly because I didnt want the book to end knowing I will have to wait another year to read about my favourite fictional characters!

Ive said it before and I will say it again Mike Craven is simply THE best crime fiction novellist in the UK!!

Thank you so much to @littlebrownbookgroup_uk for sending me an early proof it was immense!

A totally huge 5 ⭐️⭐️⭐️⭐️⭐️ read! And it just left me wanting to read the next book in the series!!

👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏

What a way to reach my reading target for the year!
Another fantastic, edge-of-your-seat read by the master M.W. Craven!

This is definitely one of my top favourite series and one of my most anticipated reads every year.
This book has got everything you could wish for. It's dark and twisty, but with some hilarious dialogue that had me snort-laughing! (As usual!)

Poe and Tilly have taken the big leap and are now private detectives with their own agency, Washington Poe & Tilly Bradshaw Gumshoes For Hire. But Poe is reluctant to take a case and is always finding a reason not to. As luck would have it—or not—the case they finally take is not the easy start they wished for. Their first client is only 15, and she's got a potty mouth on her that rivals Poe's! Her request: "Find my mother that I thought was dead."
Easy peasy... NOT!

Suddenly, they find themselves looking into the shady porn industry, and they have to try and outsmart Chinese triads. Fortunately, with Poe's brawn and lateral thinking and Tilly's brains, nothing is too difficult for these two.

I loved Esmerée, and I hope to see a lot more of her because she will definitely keep the duo on their toes, and it's always great to catch up with Estelle and one of my other favourite characters, Towler.

Lastly, the ending! I hope you are nearly finished with the next installment, Mike!

I was so pleased to be given the opportunity to read this before release. I’ve been a huge fan of the Washington Poe series from the very beginning and have read every book. It’s easily in my top three favourite series, and it’s one where I’ll always buy the next instalment because I love the characters so much.

Overall, I really enjoyed this. The plot was fast paced, there were no dull moments, and every time you thought you’d got your head around what was happening, something else was thrown into the mix. M.W. Craven has such an easy writing style that the pages just fly by, and the humour between the characters is always spot on. I was also really pleased to see Towler back. He always brings that extra bit of muscle to the team and I love what he adds to the dynamic.

The only reason this isn’t a full five stars is because I struggled a little with how quickly the relationship developed between Washington, Estelle and Esmeree. It felt a bit rushed to me, so I didn’t quite form the emotional attachment I think I was meant to. That said, I did really enjoy seeing a different side to Estelle. Her fiercer, more maternal side was lovely to read.

Overall, another brilliant addition to the series. If you’re already a Washington Poe fan, I don’t think you’ll be disappointed. I already can’t wait for the next one.
